I have looked around at several differant valve springs and came up with a little list to make it earier to compair springs however, I have a few springs that I couldn't find specs for such as the 01 LS6 springs that come with the Hot Cam kit. So if you guys would help me fill in the blanks that would be great! Also I would like to kick search in the ***** because it works about 1 out of 20 times!!!!
Spring Install Open Max lift
01 LS6 (12565117) .550" CB ?
02-03 LS6 (12586484) .570” CB ?
04 LS6 Springs (book) 90#@1.800 280#@1.250 .570” CB ?
(12499224)(web) 120#@1.800 325#@1.250 .550” CB ?

The specs you are showing for our dual springs are for the original Gold springs. Our Xtreme springs have 155@ 1.800" and 410 @ 1.140". Also the 385 on the Patriot Golds is at 1.150" not 1.200".

I believe the part number for the
02-03 LS6 and the
04 LS6 Springs
are the same springs. The 12499224 number is for a set of 16 which is much cheaper than buying them individually with the 12586484 number.
